INSTALLATION
Plan your installation carefully. Locate the radio and microphone within easy
reach, giving the operator a clear view the display. Do not locate the radio or
microphone in a position that interferes with safe operation of the vehicle.
Once the equipment location is chosen, determine the best routing for cables
and wires to connect the system. Use a rubber grommet to protect the wires
when passing through sheet metal. Avoid any route that subjects the wire to
pinching, cutting, or high heat from the engine or other vehicle component.
The radio must be used with a 12 volt, NEGATIVE GROUND electrical system.
1. Crimp the fuse holder in line with the red power lead as close to the
battery as possible.
2. Connect the red power lead to the vehicle battery POSITIVE terminal.
Using other positive voltage points in the vehicle is not recommended.
3. Connect the black lead to a good ground point on the vehicle chassis.
Connection to the negative battery terminal is not recommended.
4. Mount the antenna carefully. Follow the instructions supplied with the
antenna kit. Route the coax cable to the radio mounting location.
5. Fasten the mounting bracket securely to the desired location.
6. Mount the microphone clip securely to the desired location. The
microphone hanger clip must be grounded for proper radio operation.
Use the ground wire (item 13) if needed.
7. Mount any approved accessory speakers and route the wires to the
rear of the radio bracket.
8. Connect the power lead antenna connector, and accessory wires to
the rear of the radio.
9. Place the radio in the mounting bracket, adjust to the proper mounting
angle, and thread in the two side mounting knobs until the unit is
secure.
NOTE: Option A and B connections are logic level outputs. Consult your BK
Radio dealer before connecting accessories to these pins.
